Vincent,

>i have 85 to 86% there, so not much better.

Hmm - interesting - I had thought that 90% - 92% was the 'standard'.  What move
order do you do?  I do

1) Hash
2) Good Captures
3) Killer x 2
4) History
5) The Rest

>what is your fliprate: chance that a move which in hashtable was stored as

What is the significance of this?  Is it just the proportion of Hash moves that
produced a cutoff?

I am using quite a simple hash replacement algorithm - maybe it could be
improved.  I have two tables one is replaced if there is a deeper search the
other is replaced in all other sitiuations.  Do you think multiple hit attempts
adds much - I cann't see it myself.
